PGI_ACC_TIME lib error

Hello, setting the env variable PGI_ACC_TIME=1 using 13.6 and 13.7 versions I get the error messages "profile library not found:/opt/pgi/linux86-64/13.7/lib/ undefined symbol: _mp_cdeclp " and the same for For earlier versions than 13.5 the time measurements are fine. Why ?


Hi Manolis,

In 13.5, PGI_ACC_TIME would only record a single thread. In 13.6, our engineers began adding profiling support for multiple threads but it’s not quite ready yet.


OK Mat, thank you for your answer. Can I use the latest version 13.7 of PGPROF to get reliable time measurements for data movements and GPU computations instead of the PGI_ACC_TIME report ? I am interesting especially for multiple accelerators.
